平果铝业公司氧化铝高压溶出技术系从国外引进，一年多的试生产证明，这套技术的引进是成功的。但在试生产过程中，溶出工序闪蒸槽过料管的磨损速度过快，妨碍生产的正常进行，影响氧化铝生产的经济效益。本文通过对料浆特性和磨损机理的分析，指出料浆不溶物中高硬度、形状无规则的磨粒是使磨损过快的主要原因，并提出改善过料管结构形式，适当提高材料硬度，稳定工艺控制参数的对策，以减小过料管的磨损。
Pingguo Aluminum Company alumina high pressure dissolution technology introduced from abroad, more than a year of trial production proved that the introduction of this technology is successful. However, in the process of trial production, the wear rate of the flash tank in the dissolution process is too fast, which hinders the normal production and affects the economic benefits of the alumina production. Based on the analysis of slurry characteristics and wear mechanism, it is pointed out that high hardness and irregular shape of abrasive particles in slurry insolubles are the main reasons for excessive wear. Proposed to improve the structure of oversupply tube, to improve the hardness and stability of the material Process control parameters countermeasures to reduce the wear and tear of the material pipe.
